Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Steps: 1.Determine the overall charge of the metal complex. 2.Identify the charges of the ligands, and the numbers of e-s they donate. 3.Determine the number of valence electrons of the metal center, so that the oxidation state of the metal and charges of the ligands balance the overall charge of the complex. (E- count of metal center = Metal atom group number + ∑(charges of ionic ligands) – overall charge of the complex) 4.If metal-metal bond is present, one bond counts for one electron for each metal atom. 5.Add up the electron count of the metal center and the ligands. I'll suggest you to go through this youtube link for better understanding. https://youtu.be/H5lD0-U-TgU
